Seven bricks per square foot
Standard modular brick (7.5 × 2.25 inches with mortar joints) covers about <strong>7 bricks per square foot of wall</strong> — the number the calculator applies to your wall area after subtracting openings. Pavers and larger formats change the count; the brick's spec sheet states its actual face size.
Order from one batch
Bricks vary slightly in color between production runs called batches. Ordering the full count plus 5–10% waste <strong>from a single batch</strong> is the only way the wall reads as one surface — a pallet bought later will show. Delivery minimums and pallet quantities shape the final order more than the math does.
